Abstract
The utility model discloses a spring type coal blocking buffer plate which is characterized by comprising a primary coal blocking plate and a secondary coal blocking plate, and springs are arranged between the primary coal blocking plate and the secondary coal blocking plate. A top portion which is turned backwards by 90 degrees is arranged on the secondary coal blocking plate. A plurality of springs are evenly distributed between the primary coal blocking plate and the secondary coal blocking plate. The springs are cone spiral springs. The cone bottom faces of the springs are welded on the secondary coal blocking plate. The cone top faces are arranged on the primary coal blocking plate through screws. A buffer pad layer is fixed on the outer surface of the secondary coal blocking plate. According to the spring type coal blocking buffer plate, buffer force-relieving effect is fully used, impact loss of lump coal and the coal blocking buffer plate is lowered, lump coal rate is effectively improved, and good economical benefit and social benefit are created.
Description
Technical field
The present invention relates to keep off the coal shock absorber, specifically a kind of gear coal shock absorber that improves " lump coal rate " in the downhole coal mine transportation that is applied in.
Background technology
The existing of slat conveyer head in coal mining enterprise's production process and the first-class Coal Transport transfer point of belt feeder totally has three kinds with gear coal dash plate: (1) plate iron; (2) the outer waste and old belt of attached one deck of plate iron; (3) the outer attached one deck polyurethane of plate iron.Above three kinds of spillplates all exist installs the shortcoming fixing, that buffer action is not enough, be accompanied by the impulsive force that the running of slat conveyer and belt feeder brings, cause " lump coal " and spillplate to clash into broken serious, greatly affected the raising of " lump coal rate ", economic loss is huge.The first spillplate is exactly very stiff and demanding basically, does not have cushion effect to say; The second spillplate is enclosed the waste and old belt of one deck, the slightly better point of effect, but belt is close to plate iron, and buffer action is limited; The third spillplate is because will directly buy from producer, and cost is very high, and appended polyurethane is easily damaged after hard thing impacts, oneself is difficult to repair.
Summary of the invention
For fear of the weak point that prior art exists, the utility model provides a kind of spring loaded gear coal dash plate, and is now not enough with gear coal dash plate buffer action to solve mine, causes lump coal breaking, affects the raising problem of lump coal rate.
Technical solution problem of the present invention is taked following scheme:
Spring loaded gear coal dash plate, its constructional feature be, described dash plate comprises main spillplate and secondary spillplate, is provided with spring between main spillplate and secondary spillplate.
The utility model constructional feature also is:
Described secondary spillplate is provided with the top of 90 ° of turnovers backward.
Described spring is a plurality of, is distributed between main spillplate and secondary spillplate, and described spring is conical helical spring; Its circular cone bottom surface is welded on secondary spillplate, and the circular cone end face is arranged on main spillplate by bolt.
Described secondary spillplate outside face is fixed with one deck cushion rubber.
Described cushion rubber is fixed by bolt and secondary spillplate.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention allows the power effect by the buffering that takes full advantage of spring, reduces the shock loss of lump coal and gear coal dash plate, effectively improves lump coal rate, creates good economic benefit and social benefit.
2, to be provided with the top of 90 ° of turnovers backward be in order to screen spring to the secondary spillplate of the present invention, prevents from that solid matter from blocking to make spring ineffective.
3, the present invention's spring number used can be according to the spring hardness adjustment; The height of spring is chosen according to actual needs, also can debug by the fixed position of adjusting main spillplate the buffering effect of spring.
If 4, the present invention uses, damage is arranged afterwards, the secondary spillplate or the cushion rubber that need only the handle damage are laid down, and acknowledgment copy are changed get final product.
5, the present invention is simple in structure, productive costs is low.
Description of drawings
Fig. 1 is Application Example view of the present invention.
Number in the figure: 1 main spillplate, 2 secondary spillplates, 3 springs, 4 cushion rubbers, 5 transport planes, 6 lump coal, 7 fortune coal belt feeders.
By the specific embodiment, technical solution of the present invention is further explained explanation below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, dash plate comprises main spillplate 1 and secondary spillplate 2, and secondary spillplate is provided with the cushion rubber 4 that 4 bolts hole are used for stationary exterior surface, and the top of 90 ° of turnovers backward is set simultaneously.Be provided with spring 3 between main spillplate and secondary spillplate, spring is a plurality of, is distributed between main spillplate and secondary spillplate, and spring is conical helical spring; Its circular cone bottom surface is welded on secondary spillplate, and the circular cone end face is arranged on main spillplate by screw.Secondary spillplate outside face is fixed with one deck cushion rubber 4.
The procedure of processing of dash plate is: after the first step, cutting sheet steel, width equal slat conveyer chute, bottom and are left to slat conveyer base plate chain, top and stay enough width of the spring and turn down backward 90 ° a little more than main spillplate, four angular bit holes; Second step, divide conical helical spring anyhow three rows that the circular cone bottom surface is welded on secondary spillplate; Hole on main spillplate in the 3rd step, contrast nine of secondary spillplates spring eye position; The 4th goes on foot, with nine bolts, spring circular cone end face is fixed on main spillplate; The 5th step, the waste and old belt of cutting, width and length can surpass secondary spillplate and play the effect of buffering coal cinder; The 6th goes on foot, waste and old belt is fixed on secondary spillplate by the hole that secondary spillplate stays with bolt; So far whole spring loaded buffering spillplate completes.
As shown in Figure 1: the lump coal 6 on transport plane 5, drops on fortune coal belt feeder 7 through spring loaded buffering spillplate buffer protection at transfer point, has improved the lump coal rate of coal cinder transportation.
